The innovative Böker Plus Tactical Fountain Pen combines the versatility of modern tactical pens with the traditional writing experience of a classic fountain pen. The handle body with deep grooves is made of high-strength aluminum and feels very comfortable in the hand. The actual metal spring is located under the rear cap, which must be removed to write using the precise screw thread. To change the cartridge, the front cap can also be unscrewed using a left-hand thread. Thanks to the practical lanyard loop and sturdy stainless steel clip, the TFP is always within easy reach. Compatible with standard ink cartridges such as Parker Quink or Lamy T10
